FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed November 12, 1918, Serial No. 262,108. Renewed November 11, 1919. Serial No. 337,173.

To all whom it may concern:

Be it known that I, FRANK W. LEE, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of WVashington, have invented new and useful Improvements in Fountain-Pens, of which the following is a descriptlon This invention relates to fountaln pens and has for its primary object to provide a means whereby the ink supply of the reservoir thereof may be easily replenished.

A further object of the invention is to provide a pen which is compact in structure, reliable in operation and inexpensive to manufacture.

Other objects and advantages of the 1nvention will be apparent during the course of the following description taken in connection with the accompanying drawings.

In the drawings, forming a part of this specification and wherein like numerals are employed to designate like parts throughout the same,

Figure l is a side elevation of the device embodying my invention,

Fig. 2 is a top plan view of the same,

Fig. 3 is a central vertical longitudinal.

sectional view, the reservoir being shown as filled with ink and the several elements in a position for writing,

Fig. 4 is a similar view to that of Fig. 3, the several elements thereof being in a posltion for facilitating the filling of the reservoir.

Fig. 5 is a transverse sectional view taken on line 55 of Fig. 3, and,

Fig. 6 is a transverse sectional v1ew taken on line 6-6 of Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 10 indicates a barrel having one end thereof closed as shown at 11. Within the closed end 11 there is arranged a tube 12 to one end of which is connected a rubber reservoir 13 adapted for the reception of a quantity of ink as shown at I. The tube 12 at its outer end is provided with an ejecting port 14 and an injecting port 15. The ejecting port as clearly shown in Figs. 3 and 4 is retained in registration with an ink receiving depression 16 carried by a pen point 17 which is secured by means of ears 18 to a support 19, theears 18 being adapted to extend an appreciable distance into the sides of the support 19 as clearly shown in Fig. 5. The injecting port 15 is adapted to be closed by a spring metal valve 20 which is slidably mounted upon the barrel 10 and retained in position thereupon by means of a yoke 21 partially encircling the barrel 10 and retained in engagement thereon as clearly shown in Fig. 6.

As a means for collapsing the reservoir 13 there is provided a plate 22 which is connected by means of links 23 to the barrel 10, the links being pivotally connected to the plate 22and the barrel 10 bymeans of pivots 24 and 25 respectively. As a means for moving the plate 22 from the position shown in Fig. 3 to the position shown in Fig. 4 there is provided a link 26, one end of which. is connected to the plate 22 as shown at 27 while the other end thereof is connected, as shown at 28, to a reciprocating cap 29, the cap being mounted upon the end of the barrel 10 as clearly shown in Figs. 3 and 4.

In use, when it is desired to refill the reservoir 13, the cap 29 is moved to the position shown in Fig. 4 whereupon the plate 22 is moved to the position clearly shown in Fig. 4, thereby depressing or collapsing in reservoir 13. The pen is then dipped into a suitably quantity of ink whereupon the cap 29 is moved to the position shown in Fig. 3 allowing the plate 22 to move to the position shown in Fig. 3. The release of pressure upon the reservoir 13 permits the same to assume a normal position whereupon a quantity of ink, assuming that the valve 20 is moved to the position shown in Fig. 4, is drawn into the reservoir 13. After a desired quantity of ink is drawn into the reservoir 13 the valve 20 is moved to the position shown in Fig. 3, thus renderingthe device capable of use in that capacity for which it is obviously intended. It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States is:

A fountain pen comprising a barrel having a closed end, an elongated support carried at the closed end of said barrel, said support being provided at its sides With depressions, an elongated tube mounted Within the closed end of said barrel and provided with injecting and ejecting ports, said tube extending an appreciable distance into said barrel and an appreciable distance over the end of said support, a pen point confined between said support and the outer end of said tube, said pen point being adapted to receive upon the outer face thereof ink from the ejecting port of said tube and provided With ears adapted to extend into the depressions of said support, a yoke secured to the closed end of said barrel, a valve for closing the injecting port, said valve being adapted to slide Within said yoke, a collapsible reservoir carried Within said barrel and connected to reservoir.
